Inside `*ngFor` the second run of the styling instructions can get into situation where it tries to read a value from a binding which has not yet executed. As a result the read is `NO_CHANGE` value and subsequent property read cause an exception as it is of wrong type.

This commit cleans up `expression_type.ts` by
1. Removing the unnecessary `TypeDiagnostic` class. It's replaced by
`ng.Diagnostic`.
2. Consolidating `reportError()` and `reportWarning()` to
`reportDiagnostic()`.
This is prep work so that we could make some of the type diagnostics a
suggestion in later PRs.

`TNode.directives` was introduced in https://github.com/angular/angular/pull/34938. Turns out that it is unnecessary because the information is already present it `TData` when combining with `TNode.directiveStart` and `TNode.directiveEnd`
Mainly this is true (conceptually):
```
expect(tNode.directives).toEqual(
tData.slice(
tNode.directivesStart,
tNode.directivesEnd - tNode.DirectivesStart -1
)
);
```
The refactoring removes `TNode.directives` and adds `TNode.directiveStyling` as we still need to keep location in the directive in `TNode`

To support parallel CLI builds we instruct developers to pre-process
their node_modules via ngcc at the command line.
Despite doing this ngcc was still trying to set a lock when it was being
triggered by the CLI for packages that are not going to be processed,
since they are not compiled by Angular for instance.
This commit checks whether a target package needs to be compiled
at all before attempting to set the lock.
Fixes#35000
PR Close#35057
If ngcc gets updated to a new version then the artifacts
left in packages that were processed by the previous
version are possibly invalid.
Previously we just errored if we found packages that
had already been processed by an outdated version.
Now we automatically clean the packages that have
outdated artifacts so that they can be reprocessed
correctly with the current ngcc version.
Fixes#35082
PR Close#35079
Now `hasBeenProcessed()` will no longer throw if there
is an entry-point that has been built with an outdated
version of ngcc.
Instead it just returns `false`, which will include it in this
processing run.
This is a precursor to adding functionality that will
automatically revert outdate build artifacts.

Previously it was hard to debug an `expectOne` if the request had no match, as the error message was:
Expected one matching request for criteria "Match URL: /some-url?query=hello", found none.
This commit adds a bit more info to the error, by listing the actual requests received:
Expected one matching request for criteria "Match URL: /some-url?query=hello", found none. Requests received are: POST /some-url?query=world.

Previous to this commit, HTTP params like `{ a: '1', b: [], c: '3' }` resulted in a request like `a=1&&c=3` (note the double &&).
The ideal fix would probably be to stringify these params to `a=1&b=&c=3` like we do for empty string values. But that might be breaking as some APIs may rely on the absence of the parameter.
This fixes the issue in a compatible way by just removing the extra and unnecessary `&`, resulting in `a=1&c=3`.

This reverts commit cb142b6df9.
The intention of this commit was for a consumer of the `compile` function to
pass the `bazelHost` it returns into future invocations, reusing the
`FileCache` between them. However, first-party ngc_wrapped does not do this,
which caused a performance regression as the `FileCache` was no longer
shared between compilations.

This change changes the priority order of static styling.
Current priority:
```
(least priority)
- Static
- Component
- Directives
- Template
- Dynamic Binding
- Component
- Map/Interpolation
- Property
- Directives
- Map/Interpolation
- Property
- Template
- Map/Interpolation
- Property
(highest priority)
```
The issue with the above priority is this use case:
```
<div style="color: red;" directive-which-sets-color-blue>
```
In the above case the directive will win and the resulting color will be `blue`. However a small change of adding interpolation to the example like so. (Style interpolation is coming in https://github.com/angular/angular/pull/34202)
```
<div style="color: red; width: {{exp}}px" directive-which-sets-color-blue>
```
Changes the priority from static binding to interpolated binding which means now the resulting color is `red`. It is very surprising that adding an unrelated interpolation and style can change the `color` which was not changed. To fix that we need to make sure that the static values are associated with priority of the source (directive or template) where they were declared. The new resulting priority is:
```
(least priority)
- Component
- Static
- Map/Interpolation
- Property
- Directives
- Static
- Map/Interpolation
- Property
- Template
- Static
- Map/Interpolation
- Property
(highest priority)
```

The current logic pulls multiproviders up to the parent module's
provider list. The result is that the multi provider being defined both in
the imported ModuleWithProviders and the parent and getting an extra
item in the multi provided array of values. This PR fixes that problem
by not pulling providers in ModuleWithProviders up to the parent module.

The language service reports an error when a directive's template
context is missing a member that is being used in a template (e.g. if
`$implicit` is being used with a template context typed as `any`).
While this diagnostic message is valuable, typing template contexts
loosely as `any` or `object` is very widespread in community packages,
and often still compiles correctly, so reporting the diagnostic as an
error may be misleading to users.
This commit changes the diagnostic to be a warning, and adds additional
information about how the user can eliminate the warning entirely -- by
refining the template context type.

Sometimes, a request for definitions will return multiple of the same
definition. This can happen in at least the cases of
- two-way bindings (one of the same definition for the property and
event binding)
- multiple template binding expressions in the same attribute
- something like "*ngFor="let i of items; trackBy: test" has two
template bindings, resulting in two template binding ASTs at the
same location (the attribute span). The language service then parses
both of these bindings individually, resulting in two independent
but identical definitions. For more context, see https://github.com/angular/angular/pull/34847#discussion_r371006680.
This commit prunes duplicate definitions by signing definitions with
their location, and checking if that location signature has been seen in
a previous definition returned to the client.

There are different `DebugNode`/`DebugElement` implementations (and
associated helper functions) for ViewEngine and Ivy. Additionally, these
classes/functions, which are defined inside the `core` package, are
imported by the `platform-browser` package.
Previously, this code was not tree-shaken as expected in Ivy. #30130
partially addressed the issue, but only for the case where `core` and
`platform-browser` end up in the same closure after webpack's scope
hoisting. In cases where this is not the case, our webpack/terser based
tooling is not capable of tree-shaking it.
This commit fixes the problem, by ensuring that the code retained in Ivy
mode (due to the cross-package import) does not unnecessarily reference
`DebugNode`/`DebugElement`, allowing the code to be tree-shaken away.
This results in a 7.6KB reduction in the size of the main angular.io
bundle.
